At the physical level, UHD discs are essentially BDXL discs. If Pioneer BDXL drives without BDA's blessing can't read them at all, that's Pioneer's problem.

Meanwhile, LG was kind enough to make hardware revisions to old Blu drives going back to 2014, allowing the revised models to read BDXL discs and, by extension, UHD discs. What's your explanation for that if it's supposedly impossible to read UHD discs without being blessed by the BDA?

4K Blu-ray and BDXL are different formats. BDXL blank media is only offered in 100GB and 128GB and no 66GB disc is offered for BDXL. There exists no blank BD-66 and BD-100 4K Blu-ray discs and they are all stamped (pressed). No standalone 4K Blu-ray player supports BDXL discs according to the official specs. BDXL discs are for backing up computer data and files on BDXL BD-R drives.
